Container Background Images can also have a parallax effect applied to them. There are a range of options with regard how the image should move. These options can be found in the BG tab of any container element, once a background image has been chosen.
Below is an example of a container with a background image that has a parallax effect applied to it. The direction chosen is left, and the speed is the default .3. As you can see as you scroll, the image moves to the left. On a mobile device the image will not move as Enable Parallax on Mobile has been set to No on this container.
